Yes, "mate", it does. You're right. But remind me - how many A319s did easyJet buy? How many A320s did Air Berlin buy? And how many 787s did Air Canada buy? There's a difference in scale there. If you have 100 or so aircraft, all identical, then yes, you'll get a hell of a discount because a) the quantity is massive and b) they're all carbo copies.
I never said that it was wrong - all I did was point out that one of the reasons for the initial early success of the 787 is the pricing policy. It remains to be seen what will happen later on down the line when these airlines are locked in by their 10s and 15s but need a second tranche. They might live to rue the day they ever got in to the 787. If the A350 ends up cancelled for whatever reason, that would only exacerbate the situation!
